Subject: [dpdk-stable] [PATCH v2 0/1] net/tap: fix blocked rx packets error
Date: Mon, 23 Sep 2019 15:22:46 +0200
Message-ID: <20190923132247.16860-1-marcinx.smoczynski@intel.com> (raw)
In-Reply-To: <20190902114310.15928-1-marcinx.smoczynski@intel.com>

When OS sends more packets than are being read with a single
'rte_eth_rx_burst' call, rx packets are getting stucked in the tap pmd
and are unable to receive, because trigger_seen is getting updated
and consecutive calls are not getting any packets.

Do not update trigger_seen unless less than a max number of packets were
received allowing next call to receive the rest.

v1 to v2 changes:
 - fix typo in commit description
 - remove unnecessary compiler barrier
